MAX9712EUB+

Audio Amplifiers Overview

The MAX9712EUB+ is a mono Class D audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It delivers up to 500mW into an 8Ω load with efficiencies exceeding 85%. The device operates on a single supply voltage ranging from 2.5V to 5.5V and features a fixed internal gain of +4V/V. Key electrical specifications include a quiescent current of 4mA, shutdown current of 0.1µA, and total harmonic distortion plus noise (THD+N) of 0.01%. It utilizes a fully differential architecture with integrated click-and-pop suppression.

• Spread-spectrum modulation mode designed to reduce EMI radiated emissions by 5dB compared to conventional methods.
• Fully differential input architecture providing improved noise immunity and compatibility with DC-coupled sources.
• Integrated protection mechanisms including short-circuit and thermal-overload safeguards.

Audio Amplifiers Applications

• Cellular phones
• Portable MP3 players
• PDAs
• Portable audio devices

Audio Amplifiers Procurement Notes

Verify the specific package type against the ordering information table. The 'EUB' suffix indicates a 10-pin µMAX package. Confirm the temperature range is -40°C to +85°C. Ensure the datasheet revision matches the design requirements. Check for RoHS compliance status in the manufacturer's documentation.

Audio Amplifiers Selection Notes

Select this component for applications requiring high efficiency and minimal board space due to the filterless design. The differential input is suitable for systems needing noise immunity. Consider the 10-pin µMAX package for surface-mount assembly constraints. Verify that the load impedance supports the specified output power levels.

Audio Amplifiers Part Context

The MAX9712 series includes variants such as the MAX9712ETB (10-pin TDFN) and MAX9712EBC-T (12-bump UCSP). All variants share the same core functionality but differ in physical packaging dimensions. The EUB variant specifically utilizes the 10-pin µMAX package format.
